Year 3, Day 138: Prodigy V
Year 3, Day 161: Prodigy VI
Another failure to reach a suborbital trajectory.
Year 3, Day 184: Prodigy VII
Year 3, Day 207: Prodigy VIII
Prodigy VIII Was able to reach space, but the upper stage failed to perform its second burn.
Year 3, Day 230: Prodigy IX
Year 3, Day 299: Prodigy X
Year 3, Day 309: Prodigy XI
Year 3, Day 322: Prodigy XII
A change in the upper stage's second burn resulted it in it being placed on a de-orbit trajectory. The service module computer successfully calculated a circularization burn, but it would have been inside the atmosphere.
While this was the most successful mission to date, it was still a failure.
Year 3, Day 345: Prodigy XIII
The upper stage performs a second burn, remaining suborbital, and is then jettisoned.
After completing a full orbit, the capsule re-orients, performs its de-orbit burn, and jettisons the service module.
